... Consider the more complicated situation in which the force on the particle is given by F(x) = x − 4qx 3 This is a conservative force and the its potential energy is U(x) = − 21 x 2 + qx 4 (see Fig. 7–10). From the force, we can calculate the motion using Newton’s second law. The program that you wil ...
